When the valve is closed, flow is blocked from port 1 to port 2. However,
if the pressure in port 2 is higher than port 1, the valve will not be able to
block the fluid and it will flow from port 2 to port 1.

Note) Dew point temperature: –10°C or less
Note 1) The orifice size is just as a reference guide. Check the flow rate characteristics (conversion Cv).
Note 2) The flow rate characteristics of this product have variations.
When the highly precise flow control is required according to the system to be used, select an orifice diameter 1.3 times larger than that shown
above and install a restrictor on the downstream side of the solenoid valve to make the adjustment.
